MACHINE FOR UPSETTING RODS, BOLTS, 8L0.

SPECIFICATION forming part of Letters Patent No. 537,577, dated April16, 1895.

Application filed September 12, 1894- Serial No. 522,829. (No model.)

To all? whom it may concern.-

Be it known that I, JOSEPH MASON, a subject of the Queen of GreatBritain, residing at Boston, in the county of Suffolk and State ofMassachusetts, have invented certain new and useful Improvements inMachines for Upsetting Rods, Bolts, (he, of which the following is aspecification.

This is an upsetting machine in which the work is preferably done bymeans of a ram and plunger, and which is adapted more particularly, butnot necessarily exclusively, to upsetting or heading bolts, rods,swivels and analogous articles used in the construction of bridges andboilers and in machine shops.

The invention consists in the novel construction and arrangement ofparts hereinafter described and illustrated in the accompa nyingdrawings, in which-- Figure 1 is a plan View of my improved machine,portions of the connecting rods and bolt being operated upon beingrepresented as broken out, on account of-their length, and anotherportion being represented as broken out and still another in horizontalsection, the better to illustrate the invention. Fig. 2 is alongitudinal vertical section, a part-being in elevation and portionsbeing represented as broken out. Fig. 3 is a front elevation with aportion represented as broken out. Fig. 4 is a plan view showing thelower die, the upper die having been removed. In these figures the boltis represented as having had one end upset or headed and in position tohave its opposite end upset. Fig. 5 is an illustration of the completedproduct of the machine, i. 6., a bolt or rod upset at both ends. Fig. 6is a plan View of the lower die slightly modified in construction, andshows a plunger provided with a socket in order to surround the end ofthe bolt or rod being operated upon. Fig. 7 shows the product of themodified die illustrated in Fig. 6. Fig. 8 is a plan view of the lowerdie still further modified, and a horizontal section of a tubular boltor swivel being upset by a plunger of slightly modified shape. Fig. '9is a View of the product of the modified device shown in Fig. 8. Fig. 10is a plan view of a lower die, adapted to allow the plunger to upset aneccentric strap. Fig. 11 illustrates the product of the modificationshown in Fig. 10.

Similar letters of reference indicate corre sponding parts.

The frame of the-machine comprisesa main bed A, supported by suitablelegs or feet a, and a smaller supporting block or frame B. The bed Asupports a plate or frame 0, which sustains the lower die D and theplate'or frame O, within which is the upper die D. The inner ends ofthese plates 0 O are provided with end-pieces O which meet and areperforated to all-ow the bolt E to project through While it is beingupset. The upper die is held down upon the lower die by means of thescrew F which extends through the correspondingly threaded barf, whoseends embrace and are guided by uprightsf, the lower ends of which arebolted to the frame, (Figs. 2 and 3). As an additional safeguard toprevent possible movement or forcing apart of the dies, upright clamps dare provided, said clamps extending from and being bolted to the bed Aby boltsor screws 6, and having their upper ends bent inwardly at d overand upon the upper surface of the plate 0. The dies D D are boredhorizontally and coincidently to receive the rod E whichis to be upset,the bore being'of the exact diameter of said rod. The front portion ofthe dies is counter-bored at H from the shoulder H to the front end ofthe dies, said counter-bore being of the length and diameter of thedesired head on the rod E. This rod E, after extending rearward throughthe dieholders, extends through suitable supports or guides I, and itsfarther end rests against the wall of a recess J, formed in thesupporting blocks or bunter block J, which rests on the bed B. The twoparts of the machine, namely, the bed A, supporting the dies, and thebed B supporting the block J, are connected by rods K whose inner endsare bolted at K to the bed A. The distance between the two parts of themachine may be regulated to ac- .commodatethe length of the rod to beupset,

by means of the nuts Z on the threaded rear ends of the bolts K, and thetubes L, which can be placed on either side of the hunter block J byremoving said nuts and slipping the tubes off the rods K. Suitablewedges m (Fig. 4) may be provided for the dies, and a notched rest N maybe secured to the bed in front of the dies, to assist in sustaining theplunger in case of necessity.

is within the counter-bore H formed in the dies, and at some littledistance from the front edges of the dies. Aplunger P, of diameter tofit within said counter-bore, is placed therein against the front end ofthe rod E, being supported, if necessary, by the notched supportingpiece N. A heavy ram R is suspended by suitable means S from the ceilingor other support, and is grasped by thehandle R and impinged With greatforce against the end of the plunger P. This operation is repeated untilthe portion of the rod within the counter-bore H is upset into the shapeshown at the opposite end E, by being forced into and filling saidcounter bore. The product is shown in Fig. 5. The rod is .then releasedby loosening the screw F and, if necessary, the clamping screws 6.

In order to upset different articles, the dies must necessarily differsomewhat in shape, and frequently the same is true of the plungers. Inthe modification shown in Fig. 6 the lower die D" is provided with abore T, which is enlarged and counter-bored at T. The front end of aplain rod 15 projects into a longitudinal opening or socket in theplunger P, the result of the blows of the ram upon which is to spreadthe rod intothecounter-bore,and form it into the shape shown in Fig. 7.

In the modification shown in Fig. 8, the die is provided with a bore U,extended into an annular recess U. Atube t is placed in said bore and isformed up into the shape shown in Fig. 9 by the plunger P" of evendiameter with said tube, but having an extension smaller in diameter andprojecting into the tube.

In Fig. 10 a die D" is shown, having a recess adapted to receive thestaple shaped article V, the curved central portion V of which is upsetinto a straight thicker part, as shown in Fig. 11, by the blows of theplunger P'.

Having thus fully described my invention, what I claim, and desire tosecure by Letters Patent, is-

1. In a machine of the character described, the combination of theseparated frames A and B, the supporting plate 0 sustaining the lowerdie, the plate 0' sustaining the upper die, said plates being providedwith end pieces 0" coincidently perforated to receive the bolt which isto be upset,the lower and upper dies D D horizontally coincidently boredand counterbored and provided with the shoulder H, the uprights orguidesf, the screw F and barfarranged on said screw and guided by saiduprights, the clamps d bolted to the bed A and bent inwardly at d toextend over the upper surface of the plate 0', the hunter block J formedwith the recess J and supported by the bed B, the connecting rods Ksecured at one end to the bed A and at the other end adjustably securedto the hunter block, a plunger, and a suitably supported ram,substantially as described.

2. In a machine of the character described, the combination of theframes A B, supporting plates 0 O and dies. D D, recessed bunter block JJ, connecting rods K extending from the frame A through the hunterblock, tubes L placed upon said rods and adjusting bolts lscrewing onthe outer ends of said rods, the notched rest N secured to the bed A infront of the dies for sustaining the plunger, a plunger, and aram,substantially as set forth.

JOSEPH MASON.
